ok, if anyone cares, i've figured out one possible solution.

I noticed that if I just threw down a background colour behind my file sequence and rendered from frame 1 till the end, i would get a proper render with a bunch of empty frames preceeding the frames i desired to be rendered.

So, what i concluded from this so far, is that you can't just render in compositing starting at any frame. You have to start at frame 1. Also, the initial frames can't be empty, so you have to put something in them, of the same dimension as your other files, like a colour COPv2 or something.

sorry for the ambiguity, i was hoping it was an easy fix for a common problem.

Anyway, i tried problem solving like j.c. suggested. I used a ramp COPv2 and animated one of the colours from frame 1 to frame 300. This sequence rendered perfectly.

What i think might be causing the problems is that my images go from frame 263 to 601 instead of 1 to 300. So, anytime i try compositing where the begining frame ISN'T 1, it doesn't work except if i render in the ip or mplay.

When i use a file COPv2 with a sequence of .picnc files that don't start at frame 1, do i have to do something differently?

i'm trying to render my compositing network. i know in Outputs there's a Composite generator so i'm using it. I've selected the proper cop network and the proper cop name (that which has the render flag on aswell). But the frames just render black. This only happens when the output picture is a sequence of images. If i output to the mplay window it works just fine.

any clues why i can't render a sequence of images?
